Answer: B
Step-by-step explanation:
Since the graph is going left, the 'x' value is negative, and the 8 represents the y-intercept of the graph, so y = -2x+8
Answer: C
Step-by-step explanation:
Slope intercept form is y=mx+b where m=slope and b=y-intercept. The value for b is the y-coordinate when x=0. To find slope using the points do y-y/x-x. 0-6/8- -4= -6/12= -1/2
